The B+W 43mm T-PRO UV Filter is a general-use, clear filter designed to absorb ultraviolet light and reduce the bluish cast of daylight. Aside from the reduction of unwanted blue casts, no additional coloration or contrast is created, and adjustments to exposure are not required while using this filter. To prevent internal ghosting and reflections while providing over 99.8% light transmission, each glass surface includes multiple layers of anti-reflection coating. This Multi-Resistant Coating (MRC) also offers greater protection to the filter substrate and helps it to stay clean for longer than with uncoated filters. The Nano coating associated with this filter provides an additional eighth layer over the MRC, resulting in an improved beading effect when in contact with water for greater cleaning efficiency.

B+W filters are constructed from Schott glass for increased optical clarity and color fidelity. This filter features a thin, titanium-colored brass filter ring to minimize the potential for vignetting while enhancing durability and preventing jamming.

This UV filter is also useful as a general protective filter to leave on lenses at all times. Such filters help to keep dust and moisture from reaching your front lens element and provide additional protection in case of drops or situations where scratching could occur.
